It is not uncommon for a commit to not fix the problem mentioned in the bug report (if it *is* a problem!), or not fix it completely. Then again, changing all such subject lines to read "patch" could also already be considered an improvement.Well the real question is whether such a summary is worse than the current situation of just printing the author in the wrong field. I personally don't think it is.I think that non-obviously-wrong-but-still-wrong info is not something we should introduce. And, I think this will happen a *lot*. Maybe you can just put in artificial subjects like "Patch related to PR12345" or the like? That is correct, displays a lot better, and is at least as useful (imo).There are about 560 commits where the code highlights that the data might be suspect (usually a category mismatch).What about commits that mention multiple PRs? What do you do for those? (Are there as many of those as I think, anyway?) With normally very short subjects you could put all of them in there :-)
Depends on the context. If there look to be multiple date-stamp-author patterns and the lines are not identical we put:
[multiple commits]If there are more that three PRs and the word backport appears in the text, then it generates a 'backport' summary of the form
Backport PRs 91606, 91772, 91790, 91812, 91968 or if there are more than about 10 prs,Backport PRs 41611, 41905, 41906, 41961, 42006, 42025, 42057, 42069, 42078, 42084 and more
it's easy to change the thresholds.Otherwise we just pick the first PR found. The assumption in this case is that PRs are related and thus one summary is likely as good as another.
Yes, we can just print PR numbers, and we could print multiple numbers; but generally I find that less helpful than the summary.
Finally, note that this does *not* delete any information. The summary is added in addition to the existing text rather than replacing it.
I've attached a sample from the start of the fixed list - the full list is far too big to post to give a flavour of how the script currently works. Note that annotations of the form [checkme: ....] in the summary are for diagnostic purposes. These are where heuristics suggest that there's a higher than normal chance that the PR number is incorrect and that manual auditing is recommended. Such annotations would not be appropriate in the final conversion.
